NOVELTY - The utility model claims an LC type double-parameter sensor, composed of a first metal layer, a second metal layer, a flexible film, a conductive film, a packaging layer, an oxidation graphene film and a stretchable film; the first metal layer is composed of a first interdigital electrode, a first electrode plate and a second electrode plate connected in series; the second metal layer is composed of a second interdigital electrode, a first planar spiral inductor, a second planar spiral inductor, a third electrode plate and a fourth electrode plate connected in series. based on circuit resonance and magnetic field coupling the double-parameter sensor has two independent working modes, respectively corresponding to different equivalent circuit, the resonance frequency is not interfered with each other, respectively change along with the change of the capacitance value of the first interdigital electrode and the second interdigital electrode, so as to realize the double-parameter measurement of humidity and pressure. The utility model can overcome the disadvantages of the complexity and diversity of the traditional sensor application scene, and has wide development prospect in the wireless sensor network construction.
